Oh my gosh that's awful, but I wonder if eating unrefined coconut oil could help?
Within the last year I average two hours of sleep per night and my immune system had been failing until the last couple months or so since I got more sleep. I finally destroyed a pinworm infection that had taken over after fighting them for four months, I figured out how to physically block them .

I'm now trying to figure out why I have crawling sensations on my scalp, a small sore on the top of my scalp that is been there for weeks but is slowly getting better (poured distilled white vinegar on it, then another day Apple cider vinegar to kill any bacteria or virus since I don't know what it is). But now I can move on to figuring out why I've had tremendous hair loss on top of eyelashes itching and falling out And thinning eyebrows... I just thought I was getting old or something. Through all my research on parasites I came across something called Demadex, which apparently just about everybody has to 1° or another. When I learned about coconut or oil and started experimenting with it, I'm finding it useful everywhere!
twice now I have put the unrefined organic coconut oil all over my eyelids and eyelashes, and the same thing has happened twice: within an hour or two there appeared tiny little tan-ish dry crusts things at the very ends or tips of my eyelashes on both eyes.
I carefully took a folded paper towel and remove them reapply the coconut oil and the same thing happened but just less of them. I'm a very clean person so I guess that doesn't matter once all these disgusting parasites are opportunists if you're immune system is down apparently.

I cannot know for sure that they were Demodex on the ends of my eyelashes, but they were not there when I put on the coconut oil and I was not asleep, so what the heck are they? It makes me think that these little tiny mites were moving away from the coconut oil saturated follicles. I have lost about half of my hair over the course of a year and have heard seriously thinned out eyebrows and lost so many lashes. It never occurred to me that there could be a little parasites in my hair follicles. I wonder if they're all over my scalp. I'm going to try coconut oil all over my scalp tomorrow and maybe for a few days in a row and see what happens if the itching on the scalp stops.
I have never even thought of parasites existing until a few months ago when I figured out that I actually had pinworms, so totally gross. So since then I've been more aware of sensations in my body or on my body and trying to figure out is that just dry skin, or is it a parasite? I don't want to get to obsessed with it, but apparently I need to!

Sorry for the rambling on, but I have used coconut oil to protect my skin in ways that you probably don't want to hear about right now, but I do know that coconut oil is supposed to kill the outer covering of parasite warm skin, and from what I am learning it might also at least help or possibly get rid of Demodex mites.
Coconut oil has no chemicals and is antiviral, antifungal, and also a vermifuge for worms. I think it is likely helping with little eyelash hair follicle Demadex mites. If I were you I would just go buy organic, UNREFINED, cold-pressed coconut oil. You can find it and a lot of grocery stores now, definitely health food stores, and I just ordered more on Amazon. Just make sure you get the unrefined type of coconut oil. I've eaten some of the coconut oil in the past and never had any issues with it. You can put it on your skin and you can also ingest it.
I wish I had more to offer, but I would try eating lots of coconut oil which gets harder when it's cooled, but you can set it next to a heater and melted into liquid as well if you want. I've also read that they used finally shredded coconut for people to eat in India to get rid of worms .
Everything I am learning and have experienced with coconut oil is nothing but absolutely fantastic, healthy, and problem free. Coconut oriole is incredible and I hope that it can help you. I would eat plenty of it and even other forms of coconut like the shredded coconut or you can buy at the grocery store, maybe even coconut milk. Best wishes to you.
If it works, please let me know or publish a post for everyone to learn from it as well, hopefully for you it will help. Take care :-)
